Hello i have a 95 blazer that is the cpi model. I have had to replace the spider injector in the truck because when i pulled the top intake off i had standing pools of fuel on the passenger side. So as i replaced it i broke the plastic hoses going to the injector well i got some hose and hose clamped it and no leaks from there. My problem is now when i start the car i have gas dripping out of the exhaust flanges. I know that i throw a egr and a o2 sensor code. And on top of that i got alittle bit of a leak right after the o2 upstream sensor and before the cat. I guess im asking would the air leak and bad o2 sensor make that much fuel come out. It didnt have that fuel come out with the old one put in. Any advice would be great thanks guys.

 

Test your fuel pressure and leak down. Chances are, your repair inside the intake isn't holding.

 

Check the coolant temp sensor. It's in a vulnerable place and is brittle after years. If it breaks, the computer will think the motor is very cold and pump much fuel

 

ok i will check that out too but i have to say it is vary cold were i live around 20 degrees or less lately so yea it should be reading cold lol but thanks i will look for that too next thanks.

 

In cold weather like you describe, as your motor warms up, if the sensor is broke, it will blow black smoke and run real bad and rich.
